ELECTROLUMINESCENT FILM FOR AN OPTOELECTRONIC DEVICE

摘要

The invention relates to an electroluminescent film for an optoelectronic device comprising at least one ionic organic colourant. Optoelectronic devices that include such an electroluminescent layer have demonstrated highly satisfactory levels of radiance, efficiency and half-life of the device, that allow the potential use thereof in thin-film illumination applications, as they can operate at very low voltages, producing devices with very high energy efficiency that are also easy to produce.
